Paraguay is the world's No. 4 soybean exporter, although it
lags far behind top three suppliers the United States, Brazil
and Argentina.

A group of Paraguayan farmers asked the country's courts
last week to stop U.S. biotech giant Monsanto from charging
royalties for use of its Roundup Ready soybeans, arguing the
company's patent on the seeds had expired.
